User Authentication between two websites

shil

Hi,

Is there any possibility to authenticate an user between two websites?
I have a website through which users login and get authenticated. In
the same website I link to a different website and would like to pass
userid to the second website. My question is I want to restrict users
from going to the second website directly without getting authenticated

from the first one. Is this possible?
I know we can do this using Forms Authentication if this is in one
website.
I used below code in the web.config file of second website.
<authenticati on mode="Forms">
<forms name="Upgrade"
loginUrl="http://www.firstwebsit e.com/TestDirectory/Login.aspx"
protection="All " path="/">
</forms>
</authentication>
When I go to the second one directly, I get an error as below
*************** ***************
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make sure
that it is spelled correctly.
Requested Url: /TestDirectlry/Login.aspx
*************** ***************
Which appears the website is looking for /TestDirectory/Login.aspx in
the second web project.
Any help is appreciated.
Thanks.

Potentially. It really depends on whether they are under the same domain
root. If so, you can easily set the same machine keys (which encrypt the
server token) and pull from the different sites. Session variables will not
transfer, but you can use the same token. NOTE, however, that you have to
maintain session state for both sites in the same pool to do this.

There are ways you can do this with disparate sites, but it is a royal pain
in the butt, due to security concerns.

How to access currently logged in user from Active Directory. (Without custom login page)

by: anonymous | last post by:

Hi all, I've been searching the way to achieve the following task. But no luck so far. I have a web site(main site), which requires authentication. This authentication is set at Windows directory level, so user will see the pop up gray box in order to log in rather than custom web page. The username and password are stored at active directory level, thus this is the windows integrated security.

I need to write an ASP that requires a user to give a User Name and Password to run it.

by: Zachary Hilbun | last post by:

I need to write an ASP that requires a user to give a User Name and Password to run it. Whenever I've used this on the Web it displays a standard dialog and then offers to save the User Name and Password on my computer so that I don't have to enter it again. How is it that this standard dialog is displayed? Does the ASP (in my case C#) do this or does the Web Server do this and the ASP never knows about it? ...

Forms-Based Authentication

by: BillGatesFan | last post by:

Maybe I'm doing this the wrong way. I have an application that you log into and it validates the username and password with the database using a stored proc and if the username and password is valid then it redirects them. But I'm not using any Forms Authentication. It looks better but its pretty much doing the same thing. Is it for if you are logging in to a site? Or can it be used to log into one application? Thanks

cURL and .htaccess based user authentication

I found a nice example of ebay login using PHP and cURL at http://curl.haxx.se/libcurl/php/examples/ Is this technique applicable to sites that authenticate users using a browser-opened dialog? (like .htaccess user validation) The ebay example is a lot to take in for a newbie like me, so I'd like to have an idea first whether it is worth the time and effort modifying it.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
